 Hi,
 
 We'll need more information to diagnose this problem. Specifically, what
 version exactly of gcc and libgcj are you using? What version of (g)libc
 does your distribution use?

 Please send me the output of ls -l /lib/libc*
 
 I think that you may be using the old libc5 rather than glibc (libc6).
 
 Newwer linux kernels define a "struct sigcontext" in their headers.
 glibc has the following in its sigcontext.h:
 
 #ifndef sigcontext_struct
 /* Kernel headers before 2.1.1 define a struct sigcontext_struct, but
    we need sigcontext.  */
 # define sigcontext_struct sigcontext
 
 As a workaround, you could try changing all the references to
 "sigcontext_struct" in libgcj/libjava/include/i386-signal.h to
 "sigcontext". Please let me know if it works if you try this.
 
 Its possible that there are other issues that prevent libgcj from
 working correctly on old libc's - the best solution may be to upgrade to
 a glibc based linux distibution.

State-Changed-Why:
    This error happens if you try to build libgcj on a
    libc5 based linux system with a post-2.0 kernel. 
    
    We might be able to fix this with configurey, but given 
    that there are likely to be other subtle bugs (eg with 
    threads), we should perhaps make glibc a requirement for 
    libgcj.
